Streamlining Thionyl Tetrafluoride (SOF4) and Pentafluoro‐Oxosulfate [OSF5]− Anions Syntheses
Rationalisation des synthèses des anions de tétrafluorure de thionyle (SOF4) et de pentafluoro-oxosulfate [OSF5]−
Résumé
A one pot room temperature synthesis of thionyl tetrafluoride (SOF 4 ) from elemental fluorine (F 2 ) and thionyl fluoride (SOF 2 ) is reported. The selective decagram scale process (100 mmol) allows a quantitative preparation of SOF 4 with high purity. The solid‐state structure has also been elucidated and compared with the reported gas phase one. The use of this reagent for the formation of the emerging pentafluorooxosulfate [cat][OSF 5 ] anions led to the preparation of multiple ion‐pairs (cat=Ag, NEt 3 Me, PPN, PPh 4 ) in different organic solvents. The SuFEx reservoir ability of this anion was studied and by tuning the solvent system, the reactivity of pure thionyl tetrafluoride was observed using Ag[OSF 5 ] in THF and acetone.
